Backrooms

Depending on the level... they can range from the most horrifying thing you've ever seen to the cutest, most adorable creature in the world, but remember, appearances can be deceiving, and everything in here is waiting to kill you.

They are a labyrinthine complex of apartments that constantly changes if you blink or forget the way, mercilessly, without time, without asking you, if you lose your way... good luck finding your way out.

Backrooms are portrayed as "places that once existed and recreate them as they are remembered," which can lead to glitches, errors, or impossible architecture. All backrooms are memories; they recall a place in the original world, recreate it, and remain there for eternity. This can include people, but with obvious transfigurations and clear imperfections. They don't feel pain, and... can you eat them?

[according to the Internet] They are a complete, endless labyrinth, where every possibility is more real than ever; there are safe levels, levels with low, medium, high, and deadly danger, but some are even habitable...

Backrooms know no limits, constantly creating new levels with spaces that should be bustling with people and life, but are instead reduced to liminal places, endless corridors, and eternal nights...

(All of this is taken from the movie, not invented yet, there may be some errors and I know that the origin of the backrooms is different but I'm following the lore explained in the movie...)

Infinite, there are no limits, each one hides secrets waiting to be explored, threats hungry for your flesh, and majestic places awaiting your arrival. It depends on how far you can go here.

There are only 2 ways out (even though the internet says that at such and such a level... doing this... having that... blah blah blah, Zzz...)

The first way out is through the same wall you came in, going back until you find that same wall you went through to get out (according to the movie)

And the second is simply passing through any wall in that way, although that carries the risk of falling to other levels, and normally every time you leave the backrooms... you fall from the sky... so it's a death sentence to enter, stay, and try to get out

With the same supplies you have with you, edible items you can find on levels, and run, NEVER stop running, NEVER stop, and NEVER make too much noise... remember this... if you hear something... it probably heard you too :)

Many, hundreds and thousands that wait for the second you're not looking to attack and chase you until they kill you...

You can do whatever you want, but remember that the backrooms have power over you and will find a way to suppress you as much as possible to destroy you, no matter how strong or untouchable you are.
